Product Introduction

The GKG392 triaxial accelerometer is a widely used multi-axis accelerometer series product independently developed by RUICOM Technology, suitable for various engineering scenarios such as vibration detection and shock testing. This series supports digital interface output, with selectable RS232, RS485, or TTL communication methods, and features a configurable address code function. It supports long-distance serial networking of multiple sensors, facilitating multi-point synchronous measurement and centralized data analysis. The built-in FFT processing unit can directly output vibration frequency, velocity, and amplitude parameters, enabling users to perform rapid data analysis.

Users can dynamically adjust the sampling frequency according to the actual frequency of the measured object, thereby improving the accuracy of frequency measurement. The GKG392 adopts single-crystal silicon capacitive sensing technology. Core components include a micromachined silicon chip, a low-power ASIC for signal conditioning, a microprocessor for storing temperature compensation data, and an integrated temperature sensor. This product features low power consumption, factory calibration, robust mechanical structure, and high output stability. The new generation circuit design uses a solid-state power supply reset mechanism and has overvoltage protection. The long-term stability and typical deviation of the scaling factor across the entire range are better than 0.1%. This product series ensures long-term reliable high-precision output thanks to its robust structural design, low power consumption, and excellent deviation stability.
